Le tournant de la vie (1977)

As young dancers, they were best friends and fierce rivals. Deedee left the stage for marriage and motherhood, while Emma would become an international ballet icon. But when Deedee's teenage daughter is invited to join Emma's dance company and begins an affair with a young Russian star, the two women are forced to confront the choices they've made, the resentments they've hidden and the emotional truths they must face at the turning point.
